If there are "dead coils" on the ends of the stock springs (I don't remember), you might be able to remove them and slightly lower the car with no change in spring rates. The drop would be roughly the thickness of the removed coils times the relative placement of the spring and pivot points. If you go beyond the "dead" coils the spring rates will increase proportionately to the coils removed, as long as it is a linear spring. Progressive springs are a crap shoot.
I have cut springs SLIGHTLY in the past and benefitted from a lower center of gravity and SLIGHTLY stiffer springs. Note the SLIGHTLY. Not in half as many do, and later regret.
I have been told (repeatedly) that cutting coils is the wrong thing to do, since I am not a trained automotive engineer and that the spring spring rates may not be correct for the car. To which I reply, "Yup. You betcha." Most aftermarket spring companies will NOT publish their spring rates and those that do, are all over the place. SOOOO, which spring engineer is right? And, if the rates are not published, how do you know what you are getting and how do you know how the handling will change? On some of the Honda forums there are compilation charts of shorter springs and, WOW, are those spring rates all over the place. (I think H&R's were the best thought out - slightly proportionately stiffer in the rear.)
So, FLAME ON ! ! ! <LOL>
